Oxygen hose filled to _________ psi when checking for leaks.

When checking for leaks in an oxygen hose, it is standard practice to fill it to 50 psi. This pressure level is considered safe and effective for detecting any potential leaks without posing excessive risk. At 50 psi, the pressure is sufficient to ensure that any leaks can be easily identified, as escaping gas will produce a noticeable sound or visual indication, yet it remains within a manageable range to minimize safety concerns.

Filling the hose to a higher pressure, such as 75 psi or 100 psi, could increase the risk of accidents, as the greater pressure could lead to more significant consequences if a leak is present. Additionally, a pressure of 25 psi might not be sufficient to properly assess the integrity of the hose, as it may not provide strong enough airflow to reveal small leaks. Therefore, the choice of 50 psi strikes an appropriate balance, making it the best practice for leak detection in oxygen hoses.
